For a University assignment for a course called Real-Time Systems we had to
implement a prototype for timing analysis by tracing instructions.

The idea is that when executing a program, ptrace controls the execution and
stops after each instruction. After this the actual instruction in the memory
can be fetched. Knowing which instruction is executed you could associate this
with a certain time, add all times together for each instruction and you could
dynamically determine how long a program would run: profit!
